MIC4125YME-TR

Overview

The MIC4125YME-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features independent inverting and non-inverting outputs with a peak output current of 3A for both sourcing and sinking. The device operates within a supply voltage range of 4.5V to 20V and supports logic input levels of 0.8V (VIL) and 2.4V (VIH). Typical rise and fall times are 11ns. It is housed in an 8-SOIC package with an exposed pad, suitable for surface mount installation across a junction temperature range of -40°C to 125°C.

Feature Summary

• Provides dual independent drive channels with complementary inverting and non-inverting output configurations.
• Delivers high-speed switching performance with typical 11ns rise and fall times.
• Supports robust load driving capability with 3A peak source and sink currents.
• Compatible with low-voltage logic inputs including 0.8V and 2.4V thresholds.

Applications

• Low-side switching control for N-channel and P-channel MOSFETs
• High-speed power conversion circuits requiring fast transition times
• Industrial motor drive interfaces

Procurement Notes

Verify the specific suffix 'TR' indicates Tape and Reel packaging when ordering. Confirm the 8-SOIC-EP package variant matches the target PCB footprint. Ensure the supplier provides documentation confirming RoHS3 compliance and EAR99 classification. Cross-reference the manufacturer part number against official Microchip databases to validate authenticity and active status before finalizing procurement.

Selection Notes

Select this component when dual isolated gate signals are required from a single driver IC. The exposed pad design aids thermal management for high-current applications. Verify that the system's logic voltage levels align with the specified 0.8V/2.4V input thresholds. Ensure the operating environment remains within the -40°C to 125°C junction temperature limits defined for this package.

Part Context

This part belongs to the MIC4125 series of improved dual high-speed MOSFET drivers. It succeeds earlier Micrel designs now managed by Microchip Technology. The device is distinct from similar models like the MIC4128, which offers lower current ratings. It serves as a dedicated interface between logic controllers and power switches in compact surface-mount layouts.

Replacement Considerations

Direct substitutes include other MIC4125 variants with different packaging options such as the MIC4125YME. Check datasheets for pin compatibility and electrical parameter alignment before swapping components.

FAQ

What is the difference between the inverting and non-inverting outputs?

The inverting output provides a signal opposite to the input state, while the non-inverting output follows the input state directly, allowing flexible control schemes.

Does the exposed pad affect the electrical function?

The exposed pad primarily serves as a thermal path to dissipate heat and may be connected to the ground plane for improved performance, but it does not change the logical operation.
